The 3mm round beads that form the basis of the ring are peridot gemstone which I've woven together. The lacey outer loops are tiny faceted emerald green seed beads. There's a bit of "give" in the fit: it should work comfortably for a ring size 7 to 7-1/2. Peridot is the birthstone for August, making this a wonderful gift for the lady born in that month. Of course, if you're like me, and simply like the colour green, then it's a great gift regardless, isn't it? I have this style in other gemstones, but haven't listed them yet (I'm typing as quickly as I can), so please enquire if you don't see what you want. Naturally, it's from SPARKLE PLENTY.
